Network traffic monitoring or storage using a signed uniform resource locator

ABSTRACT

A network monitoring device may receive flow-tap information that identifies a traffic flow characteristic and a signed URL associated with a signed URL platform from a mediation device. The network device may map the traffic flow characteristic to the signed URL in an entry of a flow-tap filter that is maintained within a data structure of the network device. The network device may analyze, using the flow-tap filter, network traffic of the network to detect a traffic flow that is associated with the traffic flow characteristic. The network device may generate, based on detecting the traffic flow in the network traffic, a traffic flow copy that is associated with the traffic flow. The network device may provide, based on the signed URL, the traffic flow copy to the signed URL platform, wherein the traffic flow copy is to be accessible to an authorized user device via the signed URL.

BACKGROUND

Lawful interception includes obtaining network traffic from a network device pursuant to a lawful authority for the purpose of analysis and/or evidence. Such traffic may include signaling or network management information or content of communications.

SUMMARY

According to some implementations, a method may include receiving, by a network device of a network, flow-tap information that identifies a traffic flow characteristic and a signed uniform resource locator (URL), wherein the signed URL is associated with a signed URL platform; mapping, by the network device, the traffic flow characteristic to the signed URL in an entry of a flow-tap filter, wherein the flow-tap filter is maintained within a data structure of the network device; analyzing, by the network device and using the flow-tap filter, network traffic of the network to detect a traffic flow that is associated with the traffic flow characteristic; generating, by the network device and based on detecting the traffic flow in the network traffic, a traffic flow copy that is associated with the traffic flow; and providing, by the network device and based on the signed URL, the traffic flow copy to the signed URL platform, wherein the traffic flow copy is to be accessible to an authorized user device via the signed URL.

According to some implementations, a network device may include one or more memories and one or more processors to: receive, from a mediation device, a signed URL that is associated with a traffic flow characteristic, wherein the signed URL is associated with a signed URL platform; monitor, using a flow-tap filter, network traffic of a network to identify a traffic flow that is associated with the traffic flow characteristic, wherein the flow-tap filter includes an entry that identifies the signed URL and the traffic flow characteristic; process, based on identifying the traffic flow, the traffic flow for a transmission of the traffic flow to a traffic flow destination of the traffic flow; generate, based on processing the traffic flow, a traffic flow copy of the traffic flow; provide, based on the signed URL, the traffic flow copy of the traffic flow to the signed URL platform; and execute the transmission of the traffic flow to the traffic flow destination.

DETAILED DESCRIPTION

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

Lawful interception (LI) is a process for obtaining network traffic related to an individual (a target), as authorized by a judicial or administrative order, and providing the network traffic to a law enforcement agency (LEA) (e.g., a police department, a government agency, and/or the like). The network traffic may be lawfully intercepted at a network device (e.g., a router, a firewall, and/or the like) via flow tapping. To perform flow tapping, the network device copies or mirrors the network traffic that passes through the network device, forwards the original network traffic to an intended destination, and forwards the copied network traffic to a content destination device (e.g., associated with the LEA) that analyzes the copied network traffic.

However, the content destination device may not be available to receive the copied network traffic (e.g., the content destination device encounters an error and is unable to receive the copied network traffic, the content destination device is turned off, the content destination device is not connected to a network to receive the copied network traffic, and/or the like) and thus the copied network traffic cannot be analyzed. This may cause fraudulent activity, dangerous activity (e.g., terrorist activity, organized crime activity, and/or the like), and/or the like associated with the copied network traffic to not be detected and/or addressed by the LEA. Furthermore, computing resources (e.g., processing resources, memory resources, and/or the like) may be wasted by using such computing resources to identify, investigate, and/or rectify fraudulent activity, dangerous activity, and/or the like that could otherwise be prevented.

Some implementations described herein provide a network device (e.g., a monitoring device) that is able to perform a flow tapping process to send a traffic flow copy of a traffic flow to a signed uniform resource locator (URL) platform associated with an LEA and/or a signed URL destination (e.g., a data structure stored and/or maintained within the signed URL platform) rather than to a content destination device. In some implementations, a mediation device (e.g., an authorized tapping device, an authorized user device, and/or the like) may send, to the network device, flow-tap information that identifies a traffic flow characteristic and a signed URL that is associated with the signed URL platform and/or the signed URL destination. In some implementations, the network device may generate an entry in a flow-tap filter associated with the flow-tap information and the signed URL. The network device may analyze and/or monitor network traffic using the flow-tap filter to identify a packet that matches or corresponds to an entry in the flow-tap filter. The network device may therefore perform a flow tapping process for a traffic flow associated with the packet to send, using the signed URL, a traffic flow copy to the signed URL platform and/or the signed URL destination. One or more mediation devices may communicate with the signed URL platform and/or the signed URL destination to analyze the traffic flow copy.

In this way, the network device may provide a traffic flow copy to the signed URL platform and/or the signed URL destination, which improves an overall availability and reliability of the traffic flow copy to be analyzed by one or more mediation devices. This may increase a likelihood that fraudulent activity, dangerous activity, and/or the like associated with a traffic flow will be detected and/or addressed by the LEA. Furthermore, computing resources (e.g., processing resources, memory resources, and/or the like) may be conserved by preventing fraudulent activity, dangerous activity, and/or the like, where such computing resources would otherwise be needed to identify, investigate, and/or rectify fraudulent activity, dangerous activity, and/or the like.

FIGS. 1A-1E are diagrams of one or more examples 100 associated with network traffic monitoring using a signed URL. As shown in FIGS. 1A-1E, example(s) 100 includes a signed URL platform, one or more mediation devices (also referred to as authorized tapping devices, authorized user devices, and/or the like), one or more traffic sources (e.g., one or more origination endpoint devices), one or more traffic destinations (e.g., one or more destination endpoint devices), and/or a network device (also referred to as a monitoring device, a network monitoring device, and/or the like). As shown in FIG. 1A, the one or more traffic sources may transmit network traffic (e.g., Internet protocol (IP) version 4 (IPv4) traffic, IP version 6 (IPv6 traffic), and/or the like) to the one or more traffic destinations via the network device (e.g., a router, a switch, and/or the like). A mediation device may be a user device, a client device, and/or the like, of an LEA or other authorized organization for monitoring, analyzing, and/or the like, some or all of the network traffic that is transmitted between the one or more traffic sources and the one or more traffic destinations. As shown in FIG. 1A, the signed URL platform may be a server, a server in a cloud computing system, and/or the like, and may include a signed URL destination (e.g., a data structure stored and/or maintained within the signed URL platform). As further shown in FIG. 1A, the network device may include a flow-tap filter, a packet forwarding engine, a flow-tap interface, a routing module, and/or the like (e.g., each stored and/or maintained within respective data structures of the network device).

As shown in FIG. 1B and by reference number 110, the network device may receive flow-tap content information from the mediation device. For example, a user (e.g., a LEA representative) may interact with a user interface of the mediation device to cause the mediation device to generate and send the flow-tap information to the network device. The flow-tap information may identify at least one traffic flow characteristic and/or a signed URL. The traffic flow characteristic may be a source of a traffic flow (e.g., an address, a port, and/or the like, associated with at least one traffic source that is to provide the traffic flow), a destination of the traffic flow (e.g., an address, a port, and/or the like, associated with at least one traffic destination that is to receive the traffic flow), content data of the traffic flow (e.g., that is to be monitored and/or analyzed by the network device), and/or the like. The signed URL may specify that the signed URL platform and/or the signed URL destination is a flow tapping destination. The content data may be associated with a set of keywords, a set of key phrases, a set of word patterns, and/or the like (e.g., that are configured to trigger a flow tapping process by the network device, as described herein). In some implementations, the mediation device may generate the content data based on current and/or previous investigation reports associated with flow tapping.

The signed URL may be configured to securely permit authorized access (e.g., via the signed URL platform and/or the signed URL destination) to a traffic flow copy (e.g., that is generated by a flow tapping process, described herein) to the one or more mediation devices (e.g., to allow the one or more mediation devices to perform an authorized analysis of content data of the traffic flow). In some implementations, the flow-tap information may identify a protocol, such as hypertext transfer protocol (HTTP), associated with the signed URL platform and/or the signed URL destination (e.g., for the network device to transmit the traffic flow copy to the signed URL platform and/or the signed URL destination).

As an example, the flow-tap information may be included in a dynamic tasking control protocol (DTCP) message (e.g., a DTCP ADD message). As shown in FIG. 1B, a DTCP ADD message may include a source address field (shown as Source-Address) that indicates an address (shown as 50.50.50.2) of a traffic source that is to be monitored; a source port field (shown as Source-Port) that indicates a port (shown as 1000) of the traffic source that is to be monitored; a destination address field (shown as Dest-Address) that indicates an address (shown as 60.60.60.2) of a traffic destination that is to be monitored; and a destination port field (shown as Dest-Port) that indicates a port (shown as 2000) of the traffic destination that is to be monitored; and/or a flow-tap destination field (shown as Ftap-Dest) that identifies a signed URL (shown as “Signed URL”). Accordingly, the DTCP ADD message may indicate that the network device is to monitor network traffic for a traffic flow between the address and the port of the traffic source and the address and the port of the traffic destination, and to send a traffic flow copy to the signed URL platform and/or signed URL destination using the signed URL.

In some implementations, the network device may perform an authentication process to determine whether the mediation device is an authorized device (e.g., whether the mediation device is authorized to send flow-tap information to the network device). For example, the mediation device may send credentials of the mediation device to the network device (e.g., with the flow-tap information or as a separate data transmission). The network device may verify, based on the credentials, that the mediation device is an authorized device. Additionally, or alternatively, the network device may send the credentials to a server device (e.g., an authentication server device) that processes the credentials to determine whether the credentials are accepted or rejected. Accordingly, the network device may receive, from the server device, an authentication acceptance message (e.g., indicating that the credentials are accepted) or an authentication rejection message (e.g., indicating that the credentials are rejected). The network device may therefore determine, based on receiving an authentication acceptance message, that the mediation device is an authorized device or determine, based on receiving an authentication rejection messages, that the mediation device is not an authorized device.

In some implementations, when the network device determines that the mediation device is not an authorized device, the network device may discard the flow-tap information. In some implementations, when the network device determines that the mediation device is an authorized device, the network device may store the flow-tap information and/or analyze network traffic based on the flow-tap information, as described herein.

As shown by reference number 120, the network device may store some or all of the flow-tap information in the flow-tap filter. For example, the network device may generate, based on the flow-tap information, an entry (e.g., a flow-tap entry associated with the flow-tap information) in the flow-tap filter. As shown in FIG. 1B, the entry may include an entry identifier (shown as Tap ID), a source field (shown as Src), a destination field (shown as Dest), a content field (shown as Content), and a flow-tap destination field (shown in FIG. 1B as Tap Dest).

The network device may cause the source field of the entry to identify the source of the traffic flow identified in the flow-tap information (e.g., the address, the port, and/or the like, of the at least one traffic source that is to provide the traffic flow). The network device may cause, when a source of the traffic flow is not identified in the flow-tap information, the source field to include an “Any” designation that indicates that the entry applies to network traffic originating from any traffic source. In some implementations, the network device may cause the destination field of the entry to identify the destination of the traffic flow identified in the flow-tap information (e.g., the address, the port, and/or the of the at least one traffic destination that is to receive the traffic flow). The network device may cause, when a destination of the traffic flow is not identified in the flow-tap information, the destination field to include an “Any” designation that indicates that the entry applies to network traffic destined for any traffic destination.

In some implementations, the network device may cause the content field of the entry to include some or all of the content data included in the flow-tap information. For example, the network device may cause the content field to include the set of keywords, the set of key phrases, the set of word patterns, and/or the like of the content data. The network device may cause, when the flow-tap information does not include content data, the content field to include an “Any” designation that indicates that the entry applies to network traffic with any type of content. In some implementations, the network device may cause the flow-tap destination field of the entry to identify the signed URL in the flow-tap information (e.g., to designate the signed URL platform and/or the signed URL destination as a flow tapping destination) and/or to identify the protocol associated with the signed URL platform and/or the signed URL destination (e.g., for the network device to communicate with the signed URL platform and/or the signed URL destination). The network device may cause, when flow-tap destination information is not included in the flow-tap content information, the flow-tap destination field to include a default signed URL. In this way, the network device may map a traffic flow characteristic of the flow-tap information (e.g., the source of the traffic flow, the destination of the traffic flow, the content data of the traffic flow, and/or the like) to the signed URL in an entry of the flow-tap filter.

As shown in FIG. 1B, the flow-tap filter may include one or more entries (shown with Tap_IDs Tap_1 to Tap_n, where n is greater than or equal to 1). For example, a first entry (shown as Tap_1) includes a source field that indicates a “Src_1” traffic source, a destination field that indicates a “Dest_1” traffic destination, a content field that indicates “Content_1” content, and a tap destination field that indicates a “Signed URL_1” signed URL. As another example, a second entry (shown as Tap_2) includes a source field that indicates “Any” traffic source (e.g., indicating that the entry applies to network traffic originating from any traffic source), a destination field that indicates a “Dest_2” traffic destination, a content field that indicates “Content_2” content, and a tap destination field that indicates a “Signed URL_2” signed URL.

In some implementations, the network device may receive, from the one or more traffic sources, network traffic destined for the one or more traffic destinations. As shown in FIG. 1C and by reference number 130, the network device may monitor and/or analyze the network traffic using the flow-tap filter. For example, the network device may analyze a packet of the network traffic, which, as shown in FIG. 1C, may include information indicating a source address “SrcAdd_1” (e.g., in a source field of the packet), a destination address “DestAdd_1” (e.g., in a destination field of the packet), and/or packet content “PacketContent_1” (e.g., in a payload field of the packet).

In some implementations, the network device may determine (e.g., using deep packet inspection (DPI)) whether the packet matches or corresponds to an entry in the flow-tap filter (e.g., at least one field of the packet includes the same or similar information as at least one corresponding field of the entry). The network device may perform a lookup operation that involves scanning the flow-tap filter for an entry that matches or corresponds to the packet. For example, the network device may compare (e.g., using DPI) one or more fields of the packet and one or more respective fields of the one or more entries of the flow-tap filter. The network device may identify an entry that indicates a same or similar source address as the packet, a same or similar destination address as the packet, and/or same or similar content of the packet. For example, as shown in FIG. 1C, a first entry (shown as Tap_1) of a flow-tap filter includes: a source field that indicates a “Src_1” traffic source that is the same as or similar to the “SrcAdd_1” traffic source indicated by the source field of the packet; a destination field that indicates a “Dest_1” traffic destination that is the same as or similar to the “DestAdd_1” traffic destination indicated by the destination field of the packet; and a content field that indicates “Content_1” that is the same as or is similar to “PacketContent_1” content indicated by the content field of the packet (e.g., a set of keywords, a set of key phrases, a set of word patterns, and/or the like, of the content field correspond to or match content of the content field of the packet).

In some implementations, the network device may identify, based on the source address field and the destination address field of the packet, a particular traffic source (shown in FIG. 1C as traffic source 1) and a particular traffic destination (shown in FIG. 1C as traffic destination 1) associated with the packet. As shown by reference number 140, the network device may detect (e.g., based on determining that the packet matches or corresponds to an entry in the flow-tap filter) a traffic flow that includes the packet and/or one or more additional packets of the network traffic that are transmitted from the particular traffic source to the particular second traffic source. For example, the traffic flow may include a particular number of packets transmitted from the particular traffic sources to the particular traffic destination after the network device determines that the packet matches or corresponds to an entry in the flow-tap filter (e.g., the next 100 additional packets, the next 1,000 additional packets, the next 10,000 additional packets, and/or the like, after the packet). As another example, the traffic flow may include any number of packets transmitted, from the particular traffic source to the particular traffic destination, during a time period after the network device determines that the packet matches or corresponds to an entry in the flow-tap filter (e.g., for 1 second, 10 seconds, 20 seconds, and/or the like, after the network device determines that the packet matches or corresponds to an entry in the flow-tap filter).

In some implementations, the network device may notify, based on determining that the packet matches or corresponds to an entry in the flow-tap filter and/or detecting the traffic flow, the mediation device that the packet and/or the traffic flow was identified. For example, the transmitting network device may send, to the flow-tap destination address (e.g., of the mediation device and/or one or more other mediation devices) indicated by the entry in the flow-tap filter, a message indicating that a packet and/or traffic flow matches or corresponds to the entry. In some implementations, the network device may receive, from the mediation device (or another mediation device), a response indicating that the network device is to perform a flow tapping process on the traffic flow (e.g., to provide a traffic flow copy to the signed URL platform and/or the signed URL destination). The network device therefore may process the traffic flow as described herein in relation to FIG. 1D. Additionally, or alternatively, the network device may receive, from the mediation device (or another mediation device), a response indicating that the network device is to not perform a flow tapping process on the traffic flow. The network device may therefore route the traffic flow using a typical routing process.

As shown in FIG. 1D and by reference number 150, the network device (e.g., using the packet forwarding engine of the network device) may process the traffic flow. In some implementations, the network device may process the traffic flow to generate a traffic flow copy that corresponds to the traffic flow. For example, the network device may duplicate each packet of the traffic flow to generate the traffic flow copy. The network device, based on the entry of the flow-tap filter associated with the traffic flow, may include the signed URL from the flow-tap destination field of the entry in the traffic flow copy (e.g., the network device may encapsulate each packet of the traffic flow copy with the signed URL). As another example, the network device may extract payload data (e.g., content data) of the traffic flow (e.g., from the respective payload fields of the packets that comprise the traffic flow) and generate new packets that include the extracted payload data to generate the traffic flow copy. Each new packet of the traffic flow copy may include the signed URL from the flow-tap destination field of the entry.

Additionally, or alternatively, the network device may process the traffic flow to transmit the traffic flow to the traffic destination associated with the traffic flow (e.g., as if the network device did not perform a flow tapping process). For example, the network device may generate and/or modify routing data of the traffic flow to indicate that the network device received the traffic flow and/or is to route the traffic flow to the traffic destination associated with the traffic flow. The network device may include the routing data in each packet of the traffic flow (e.g., the network device may encapsulate each packet of the traffic flow with the routing data).

As shown by reference number 160, the network device (e.g., using the flow-tap interface of the network device) may send the traffic flow copy to the signed URL platform and/or the signed URL destination. For example, the network device may send, based on the signed URL included in the packets of the traffic flow copy, the traffic flow copy to the signed URL platform and/or the signed URL destination. Additionally, or alternatively, the network device may identify a communication protocol (e.g., an HTTP protocol, an IP protocol, a DTCP protocol, and/or the like) of the signed URL platform and/or the signed URL destination (e.g., for receiving the traffic flow copy from the network device). For example, the network device may identify the communication protocol in the flow-tap destination field of the entry of the flow-tap filter. The network device may therefore send the traffic flow copy to the signed URL platform and/or the signed URL destination according to the communication protocol. For example, when the communication protocol is HTTP, the network device may send the traffic flow copy to the signed URL platform and/or the signed URL destination using a PUT command or a POST command.

In some implementations, the signed URL platform may receive the traffic flow copy from the network device and may cause the traffic flow copy to be stored in the signed URL destination (e.g., to allow the traffic flow copy to be accessible to the one or more mediation devices as described herein). Additionally, or alternatively, the signed URL destination may directly receive the traffic flow copy from the network device and may store the traffic flow copy.

As shown by reference number 170, the network device (e.g., using the routing module of the network device) may route the traffic flow to the traffic destination associated with the traffic flow. The network device may route the traffic flow to the traffic destination without any indication to the traffic destination that a flow-tapping process occurred (e.g., without notifying the traffic flow destination that the traffic flow copy was generated).

As shown in FIG. 1E and by reference number 180, a mediation device of the one or more mediation devices may communicate with the signed URL platform and/or the signed URL destination to access the traffic flow copy. For example, the mediation device may use the signed URL to access the signed URL platform and/or the signed URL destination to obtain the traffic flow copy. In some implementations, the network device may provide a notification to the mediation device that the traffic flow copy has been provided to the signed URL platform. The mediation device may therefore communicate with the signed URL platform to obtain the traffic flow copy from the signed URL destination.

In some implementations, the mediation device may process the traffic flow copy to determine a context analysis (e.g., determine whether the traffic flow copy is associated with fraudulent activity, dangerous activity, and/or the like). The mediation device may extract payload data of the traffic flow copy (e.g., from respective payload fields of the packets that comprise the traffic flow copy) and analyze the payload data (e.g., using natural language processing) to determine whether the traffic flow is associated with fraudulent activity, dangerous activity, and/or the like.

Furthermore, two or more devices shown in FIGS. 1A-1E may be implemented within a single device, or a single device shown in FIGS. 1A-1E may be implemented as multiple, distributed devices. Additionally, or alternatively, a set of devices (e.g., one or more devices) shown in FIGS. 1A-1E may perform one or more functions described as being performed by another set of devices shown in FIGS. 1A-1E.

A method, comprising: analyzing, by a network device and using a flow-tap filter, network traffic to detect a traffic flow that is associated with a traffic flow characteristic, wherein the flow-tap filter maps the traffic flow characteristic to a signed uniform resource locator (URL), and wherein the traffic flow characteristic is at least one of a source of the traffic flow, a destination of the traffic flow, or content data of the traffic flow; generating, by the network device, a traffic flow copy that is associated with the traffic flow; and providing, by the network device, the traffic flow copy to a signed URL platform associated with the signed URL, wherein the traffic flow copy is to be accessible, via the signed URL, to an authorized user device to enable the authorized user device to determine whether the traffic flow copy is associated with one or more of fraudulent activity or dangerous activity.
 2. The method of claim 1, wherein generating the traffic flow copy that is associated with the traffic flow comprises: duplicating packets of the traffic flow to generate the traffic flow copy.
 3. The method of claim 1, further comprising: storing flow-tap information in the flow-tap filter, wherein the flow-tap information includes the traffic flow characteristic, and wherein the flow-tap information is included in a dynamic tasking control protocol (DTCP) message.
 4. The method of claim 1, further comprising: forwarding the traffic flow to a traffic flow destination that is identified in the traffic flow.
 5. The method of claim 1, wherein the source of the traffic flow comprises an address or a port associated with at least one traffic source that is to provide the traffic flow and the destination of the traffic flow comprises one or more of an address or a port associated with at least one traffic destination that is to receive the traffic flow.
 6. The method of claim 1, further comprising: identifying a communication protocol of the signed URL platform, the communication protocol comprising: a hypertext transfer protocol (HTTP) protocol, an interne protocol (IP), or dynamic tasking control protocol (DTCP) protocol; and wherein providing the traffic flow copy to the signed URL platform associated with the signed URL comprises: providing the traffic flow copy to the signed URL platform according to the communication protocol.
 7. The method of claim 1, wherein the signed URL specifies that one or more of the signed URL platform or a signed URL destination is a flow tapping destination.
 8. A device, comprising: one or more memories; and one or more processors to: analyze, using a flow-tap filter, network traffic to detect a traffic flow that is associated with a traffic flow characteristic, wherein the flow-tap filter maps the traffic flow characteristic to a signed uniform resource locator (URL), and wherein the traffic flow characteristic is at least one of a source of the traffic flow, a destination of the traffic flow, or content data of the traffic flow; generate a traffic flow copy that is associated with the traffic flow; and provide the traffic flow copy to a signed URL platform associated with the signed URL, wherein the traffic flow copy is to be accessible, via the signed URL, to an authorized user device.
 9. The device of claim 8, wherein the content data is associated with one or more of: a set of keywords, a set of key phrases, or a set of word patterns.
 10. The device of claim 8, wherein the signed URL is configured to securely permit authorized access to the traffic flow copy to enable an authorized analysis of the content data.
 11. The device of claim 8, wherein the one or more processors, to generate the traffic flow copy, are to: encapsulate each packet of the traffic flow copy with the signed URL.
 12. The device of claim 8, wherein the one or more processors, to generate the traffic flow copy, are to: copy traffic data of the traffic flow; extract content data from the traffic data; and generate the traffic flow copy associated with the traffic flow to include the signed URL and the content data.
 13. The device of claim 8, wherein the one or more processors are further to: identify a communication protocol of the signed URL platform; and wherein the one or more processors, to provide the traffic flow copy to the signed URL platform associated with the signed URL, are to: provide the traffic flow copy to the signed URL platform according to the communication protocol.
 14. The device of claim 8, wherein the one or more processors are further to: store flow-tap information in the flow-tap filter, wherein the flow-tap information includes the traffic flow characteristic, and wherein the tap flow information is included in a dynamic tasking control protocol (DTCP) message.
 15. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by one or more processors of a network device, cause the one or more processors to: analyze, using a flow-tap filter, network traffic to detect a traffic flow that is associated with a traffic flow characteristic, wherein the flow-tap filter maps the traffic flow characteristic to a signed uniform resource locator (URL), and wherein the traffic flow characteristic is content data of the traffic flow; generate a traffic flow copy that is associated with the traffic flow; and provide the traffic flow copy to a signed URL platform associated with the signed URL, wherein the traffic flow copy is to be accessible, via the signed URL, to an authorized user device to enable the authorized user device to determine whether the traffic flow copy is associated with one or more of fraudulent activity.
 16. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed, are further to cause the one or more processors to: identify a communication protocol of the signed URL platform; and wherein the one or more instructions, that cause the one or more processors to provide the traffic flow copy of the traffic flow to the signed URL platform, cause the one or more processors to: provide the traffic flow copy to the signed URL platform according to the communication protocol.
 17. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed, are further to cause the one or more processors to: store flow-tap information in the flow-tap filter, wherein the flow-tap information includes the traffic flow characteristic, and wherein the flow-tap information is included in a dynamic tasking control protocol (DTCP) message.
 18. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, that cause the one or more processors to generate the traffic flow copy, cause the one or more processors to: duplicate packets of the traffic flow to generate the traffic flow copy.
 19. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed, are further to cause the one or more processors to: provide a notification to the authorized user device that the traffic flow copy of the traffic flow has been provided to the signed URL platform, or transmit the traffic flow to a traffic flow destination.
 20. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, that cause the one or more processors to provide the traffic flow copy of the traffic flow to the signed URL platform, cause the one or more processors to: provide the traffic flow copy to the signed URL platform using a PUT command or a POST command.
